We are quite sure that's NOT what happens because the light coming out would have different properties, but that's a popular misconception. The photon doesn't collide with a single silicon atom to slow it down, it's interacting with the structure of the glass which physicists call a phonon.

So a photon enters a glass medium, collides with a silicon atom, the silicon atom because of the energy gain pushes out a silicon photon, this goes on until the energy , not the original photon exits the glass at the speed of light. Then then the slow down is caused by the time delay the original energy takes to transit the atoms, is this the permeability?
phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, like solids and some liquids.
That rather sounds like its interacting with a field of some kind.

How Current Loops and Solenoids Curve Space-time
Andre Fuzfa
Namur Center for Complex systems (naXys),
University of Namur, Belgium
(Dated: December 15, 2015)
The curved space-time around current loops and solenoids carrying arbitrarily large steady electric currents is obtained from the numerical resolution of the coupled Einstein-Maxwell equations in cylindrical symmetry. The artificial gravitational field associated to the generation of a magnetic field produces gravitational redshift of photons and deviation of light. Null geodesics in the curved space-time of current loops and solenoids are also presented. We finally propose an experimental setup, achievable with current technology of superconducting coils, that produces a phase shift of light of the same order of magnitude than astrophysical signals in ground-based gravitational wave observatories.

lol I like you.
But honestly, particles can just pop into existence? Like... bam, something from nothing?
Or is the nothing possibly the electronic and magnetic fields?
Sure they can. You just need enough energy and, I'm pretty sure although this isn't something I diddle with often, a charge or charge gradient.
This is where the long form of E=MC2 comes in. You can swap energy for matter (and momentum, in the long form) as long as you got equal or more E to match the M you want to concoct.
In the case of a photon, you don't have a lot of extra boundary conditions to satisfy, so it's pretty likely you'll get photons. But, consider the annihilation of matter and antimatter. You get a wad of photons, and possibly other particle production as well just due to the energy density. And the matter and antimatter go bye bye.
But you can make more than photons that way. If you have enough energy, you can create an electron and a positron simultaneously, or a proton and an antiproton, etc.
This isn't something pie-in-the-sky, it happens all the time, if you like fiddling around with cloud chambers at home (and who doesn't) you can do it yourself.
